"Why does the video slow down or stop during playback?
Depending upon your Internet connection, some videos may take longer to load. Wait for your video to load fully (as represented by the grey progress bar within the video control slider) before playing it." - Dailymotion
The videos are streamed to your computer, meaning that the rate of playback is based on your internet connection speed. If you are on a slow connection, or you are using a lot of your bandwidth for other things (torrents, streaming music, downloading, etc.), you can click the little play button in the left hand bottom corner of the video, then click the same button again (which will turn to a pause button after you click it the first time). This will start to buffer the video.
